Abstract
Abstract The system includes first and second hoppers or magazines located adjacent respective ends of a conveyor. The first magazine includes a three-sided enclosure with a vertically movable magnetic plate situated therein for holding thereagainst elongate objects having magnetizable material therein. A plurality of pawls which are deflectable inwardly of the plate are situated adjacent the movable plate. They are deflected inwardly when the plate is moved downwardly and engage and hold objects in a lowered postion when the plate moves upwardly, the plate slidingly engaging the objects during the upward movement. The lowermost position to which an object is moved is adjacent the conveyor which engages the object and moves it laterally from the first magazine. The second magazine includes a stationary magnetic plate for holding a plurality of the elongate objects thereagainst. A vertically reciprocal pushing mechanism is located beneath the plate and is operable to sequentially push objects from the conveyor onto the plate. The pushing mechanism includes an air cylinder, two rods connected to the piston rod of the cylinder and an elongate head which is movable transversely of the long axis thereof and which is detachably connected to the rods.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
In a system for storing elongate objects each having magnetizable material therein and for sequentially moving the objects transversely of the long axis of each object onto a conveyor, a magazine including a generally upright member having means for magnetically holding a plurality of objects thereagainst, deflectable pawls situated adjacent said upright member and deflectable inwardly of said plate, and means for moving said upright member downwardly to move the objects held thereto from an upper position downwardly over said pawls to a lower position and for moving said upright member upwardly as said pawls engage the objects and hold the same in the lowered positions the lowermost position being adjacent the conveyor.
Claim 2
Dependent Claim

Claim 8
Independent Claim
190 words
A system for loading objects onto, and unloading objects from, a conveyor, each object having magnetizable material therein, said system including a first magazine located adjacent one end of a conveyor, a second magazine located adjacent the other end of the conveyor, said first magazine including a generally upright member having means for magnetically holding a plurality of objects thereagainst, deflectable pawls situated adjacent said upright member and deflectable inwardly of said plate, and means for moving said upright member downwardly to move the objects held thereto from an upper position downwardly over said pawls to a lower position and for moving said upright member upwardly as said pawls engaged the objects and hold the same in the lowered positions, the lowermost position being adjacent the conveyor, said second magazine including a generally upright plate having means for magnetically holding a plurality of objects thereagainst, pushing means for pushing each object from the conveyor onto the generally upright plate, said pushing means including an elongate head movable transversely of the long axis thereof, power means for moving said head and means for detachably connecting said head to said power means.
Claim 9
Independent Claim
190 words
A system for loading objects onto, and unloading objects from, a conveyor, each object having magnetizable material therein, said system including a first magazine located adjacent one end of a conveyor, a second magazine located adjacent the other end of the conveyor, said first magazine including a generally upright member having means for magnetically holding a plurality of objects thereagainst, deflectable pawls situated adjacent said upright member and deflectable inwardly of said plate, and means for moving said upright member downwardly to move the objects held thereto from an upper position downwardly over said pawls to a lower position and for moving said upright member upwardly as said pawls engaged the objects and hold the same in the lowered positions, the lowermost position being adjacent the conveyor, said second magazine including a generally upright plate having means for magnetically holding a plurality of objects thereagainst, pushing means for pushing each object from the conveyor onto the generally upright plate, said pushing means including an elongate head movable transversely of the long axis thereof, power means for moving said head and means for detachably connecting said head to said power means.
Claim 10
Dependent Claim
51 words
The system according to claim 7 wherein said second magazine is constituted solely by said pushing means and said upright plate which does not obstruct the path of movement of objects on the conveyor as and when an object is carried past said second magazine when said power means is inoperative.
